Application filed. November 23, 1908. Serial No. 464,069.

To all whom it may concern:

Be it known that 1, JAMES H. MONT- GOMERY, a citizen of the-UnitedStates of America, residing in the city and county of Denver and Stateof Colorado, have invented a new and useful Coin-Controlled AdvertisingDevice, of which the following is a specification.

My invention relates to improvements in coin controlled advertisingdevices, and the objects of my invention are: First, to provide a coincontrolled stamp mill machinery starting advertising device. And second,to provide a display and machinery contain ing case, in which aminiature operative ore stamping mill can bestarted to running by a coincontrolled mechanism, and will run for a predetermined period of time. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which: T

Figure 1, is a side elevation of the improved advertising device andsupporting casing, the door being removed to afford a view of themechanism for operating the device. And Fig. 2, is a vertical sectionalview through the device, affording a front View of the stamp mill andoperatingmeohanism.

Similar numerals of reference refer to similar parts throughout theseveral views.

Referring to the drawings, the numeral 1, represents a case of wood ormetal, which is preferably square in cross section, but may be made ofany desired form of cross section. This case 1, is preferably dividedinto two parts, the base portion 2, and the cap ortion 3. The baseportion 2, is provided with an entrance door 2", which is provided witha lock and key. The bottom portion of the base is provided with anelectric motor 4, which rests on and is secured to a floor portion 5,formed across the bottom portion of the base of the case. This motor 4,is provided with a driving pulley 6, which is connected by a rubber belt7 to a pulley 8, which is mounted on a shaft 9, which is positionedabove the motor in the central portion of the base, and is journaled inbearings 10, formed on the end of an arm 11, which is pivotally mountedat its other end in bearings 12, which are secured to one of theadjacent inside walls 13, of the base of the case. A small pulley 14; isalso mounted on this shaft 9, which is connected by a belt 14 to apulley 15, that is mounted on the end of the cam shaft of the stampmill, which is located within the cap of the case, as will be fullyexplained hereinafter.

Between the motor and the driving pulley 8, of the shaft 9, a ratchettoothed wheel 16, is mounted, on a shaft 17, which is journaled in boxes18, that are secured to shelves 19 and 20, which are placed across thebase above the motor to receive them. The peripheral surface of thisratchet wheel is provided with a continuous circumferential row ofratchet teeth of'short circular pitch, which are engaged by a pawl 21,the pivotal end 22 of which is pivotally mounted on an ecoentricallyarranged pin 22 on the end of the shaft 9, and held thereon by a nut 23,which is threaded to the end of the pin. The pawl rests by its weight inengagement with the teeth, and the eccentric is arranged with throwenough to move the pawl one tooth on the periphery of the ratchet wheel.

A coin receiving tube 24, is placed vertically in the base against thefront end 25 of the base, and extends from its top cover 26 to the lowerend of the base, and enters the top of a box-shaped recess 27, formed inthe base. This tube registers with a coin receiving slot adapted toreceive a nickel denomination of coin easily, and the tube 24 isprovided with an aperture that is wide enough to receive the nickelsidewise and allow it to drop in a sidewise position thtough it into theapartment at its lower en An angled recess 28, is cut into the insideedge of the coin tube, which is deep enough to allow the edge of thecoin to be exposed, and project beyond the surface of the slot, as itdrops through the tube, and a coin stopper plate 29 is pivotallysupported to stand normally in this recessed notch and stop the coin asit falls. This coin stopper device also comprises the motor startingdevice, and it comprises a lever 30 pivotally mounted at its endadjacent to the coin tube, on a pin 31, which is journaled in bearings32, which are secured to a shelf 83, that extends across the base toreceive them. The opposite end of this motor starting lever extends overthe shaft 17 of the ratchet wheel, and is provided with an adjustablepin 34, at its end, which is preferably threaded to it and which isarranged to extend through it and bear on the shelf 33. This adjustablepin is adapted to adjust the lever in ahorizontal plane relative to theengagement of the coin with its coin engaging end, and to a cam 35,which is mounted on the shaft 17, and that is arranged to engage thelever at each revolution of the ratchet wheel and its shaft, and raisethe lever high to move its coin engaging end out of the path of the coinand release it, and stop the motor, as will be explained more fullyhereinafter.

The lever 30 is provided with a recess 36, into which the cam moves andreleases the lever after it has raised the lever high enough to releasethe coin. The coin tube is connected by an electric wire 37, to oneterminal binding post of one side of the motor, and another circuit wire38 is connected at one end to the opposite binding post of the same sideof the motor and extends out of the base to a source of supply. Acircuit wire 39 is also connected at one end to the coin engaging plate,and is extended out of the base to a source of supply. The supply ofelectric current may be taken from a terminal socket of an electric wirethat leads to a dynamo, or from an ordinary lamp socket, and the twocircuit wires may be connected to a plug adapted to fit the socket. Bythis means an electric circuit is between the coin tube and the coinstopper plate by the coin, which starts the motor, and this circuit isbroken by the release of the coin from the stopper lever by the cam onthe sliaft 17, as will be fully explained herein a ter.

The cap 26 of the case, rests on top of and is secured to the baseportion 2 of the case. This cap is in the form of a casing, comprising afront side 40, ends 41 and 42, and

an inclined top portion 43, which are all of glass, while its rear orback portion 44 is preferably made of metal. The lower edges of theglass rest in grooves formed in the top of the base 2, and the sides andfront and inclined top are connected preferably by small angle plates,and the sides are connected to the back plate 44. A plate 45, projectsvertically upward from the upper end of the back plate, on which aninscription which reads as follows, is placed: Drop a nickel in the slotand see the stamp mill run. This glass cap is set over the stamp mill46, which consists of two batteries of five stamps each. These batteriescomprise the battery frames 47, the mortars 48 and 49, and the stems 50.The stems 50 are provided with tappets 51 and a cam shaft 52 extendstransversely along the back of the stems of both batteries, and isjournaled in boxes which are secured to the back of the frames, and uponone end of this cam shaft the pulley 15 is mounted, which is connectedby the belt 14 to the small pulley 14 of the shaft 9, as abovedescribed. The cam shaft is provided with a cam for each stamp tappet,which is keyed to the shaft in engagement with its respective tappet, todrop intermittently and in random order. The mortar of each battery isprovided with a screen 55, and two amalgamating plates 56, and theirsupporting troughs 57, are placed against the front of the mortars atthe lower edge of the screens. The rear sides of the mortars areprovided with feed chutes 58, and a feed spout 59 is placed to receiveore from a hopper 6O placed above it, and a feed chute 61 extends fromthe outside of the rear side of the cap into the hopper. A completeminiature ore crushin stamp mill is thus exhibited to the view of thedropper of the coin in the slot, through the glass front of the cap,which will run in an operative manner when a coin is dropped in theslot.

The operation is as follows: When av nickel of coin money is dropped inthe slot, it drops down into the coin tube until it strikes the coinstopper lever, where it stops, resting against the coin stopper lever,which closes the electric current circuit between the source of electriccurrent supply through the wires 37, 38, and 39, and the coin tube andcoin stopper plate, and the current flows into the motor and starts itto running, and the motor 9 drives the shaft 9 through the medium of thebelt 7, and the pulley 14 of the shaft drives the pulley 15 on the camshaft through the medium of the belt 14*; the cams 52 are thus rotatedand each cam bears against its stamp stem tappet and raises it as thecam rotates, and allows it to drop against the bottom of the mortar.

All of the ten stamps are raised and dropped in the operative order of afull sized practically operating ore stamping mill.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

1. In a coin-controlled display device, a base, operating mechanism insaid base, a shaft adapted to be rotated by said mechanism, a pawlcarried by said shaft, a wheel arranged to be intermittently rotated bysaid pawl, a shaft for the wheel, a cam on the wheel shaft, acoin-stopping lever adapted to be moved by said cam to release the coinand open the circuit of said electrical mechanism after a completerevolution of said wheel.
